I know of skeletons in trees on the edge of the ridge on which the home station was built.

These are said to be for the most part the bodies of worthless women or babies.
In the coastal districts there are platforms in trees on which dead bodies were laid.

In some places corpses are tied up in a sitting posture.

The tying, they say, is to keep them secure when spirits come about, or body-snatchers for poison bones.
In some places the graves are covered with a sort of emu egg-shaped and sized lumps of copi; and also, when a widow's term of mourning was over, she would take the widow's cap--which was a sort of copi or gypsum covering put on wet to her head--and place it on the grave of her husband.
On the Narran the widows plaster their heads with copi or bidyi, as they call it, but so thinly that it cakes off.

They renew it, and keep their heads covered with it for the allotted term of mourning, then just let it gradually all wear off.
Those widows' caps, having the imprint of nets inside them, are very old; for hair nets have been out of fashion for very many years in camp-land, so such rank as antique curios.
I don't think the small girl who thought when she grew up she'd choose to be a widow, would have thought so if she had been born black.
When a black woman's husband dies she has to cover herself with mud, and sleep beside a smouldering smoke all night.
